Polymers having silicon containing end groups and a process for their preparation

Abstract

Abstract THIS INVENTION PROVIDES A POLYMER CURABLE WITH MOISTURE, SAID POLYMER PREPARED BY POLYMERIZING AT LEAST ONE ETHYLENICALLY UNSATURATED MONOMER, REACTIVE WITH AN AZO NITRILE AND FREE OF FUNCTIONAL GROUP REACTIVE WITH ARYLOXYSILANES AND ALKOXYSILANE, WITH AN AZONITRILE OF THE FORMULA R-SI(-R'')(-R")-(CH2)2-Y-C(-CN)(-R''")-N=)2 WHERE R IS ALKYL, FLUORO-SUBSTITUTED ALKYL WHEREIN THE FLUORO SUBSTITUENT IS NO CLOSER THAN A GAMMA POSITION WITH RESPECT TO SI, PHENYL, LOWER ALKYL-SUBSTITUTED PHENYL, FLUORO-SUBSTITUTED PHENYL, BENZYL OR LOWER ALKYL-SUBSTITUTED BENZYL; R'' IS LOWER ALKOXY, ARYLOXY, ALKARYLOXY, LOWER ARALKOXY; R" IS INDEPENDENT OF R AND R'' AND IS ANY OF THE GROUPS REPRESENTING R OR R''; R"'' IS A LOWER ALKYL, LOWER ALKYL-SUBSTITUTED PHENYL, BENZYL, OR LOWER ALKYLSUBSTITUTED BENZYL WHEREIN SUBSTITUTION IS AT OTHER THAN AN ALPHA POSITION; Y IS A SATURATED LOWER ALKYLENE. SOME POLYMERS ARE PARTICULARLY USEFUL AS MOISTURE CURABLE CAULKS.
